Self-quarantine tips for those infected or at risk of the coronavirus

COLUMBUS, Ohio - New antibody testing shows that symptoms for several cases of the novel coronavirus were present in Ohio in January, according to state health officials.

Ohio Department of Health Director Dr. Amy Acton said Monday that symptoms for at least five confirmed cases of COVID-19 in five different counties began in January, the earliest of which dates back to January 7.

“We’re doing a lot more investigation,” Acton said. “Our disease detectives are going back to take a look at that and see if they were associated with travel.”

Acton said as additional antibody testing is done, health officials will learn more about how long COVID-19 has been in the state and how long it has been spreading. The department will begin testing 1,200 volunteers in the state next week for coronavirus antibodies as part of its research.

Meanwhile, Ohio began the process of reopening its economy, with retailers being allowed to conduct business starting on May 12. Salons, barbershops, outside restaurants and patios can open starting May 15, followed by restaurant dine-in locations beginning on May 21.
